TOY.

Application filed. February 24, 1923. Serial No. 620,943.

To all whom it may concern:

Be it known that I, FRANK D. Kim, a subject of the Emperor of Japan, residing at San Francisco, in the county of San Francisco and State of California, haveinvented new and useful Improvements in Toys, of which the following is a specification.

This invention relates to improvements in toys and resides in the provision of a novel and amusing aerial toy wherein upon actuation of its simply constructed mechanism, a projectile member will be rapidly rotated and caused to rise and sail in the air after the fashion of a helicopter.

An object of the invention is to provide a toy of the character described in which novel means is provided for imparting a rotary movement to and launching the propeller like aerial member, which means is inexpensive, small, compact, not liable to ready derangement or breakage, easy to operate and conveniently mounted on a handle.

Another object is to provide in a toy of the character described a novel form of aerial member or projectile which comprises a two blade propeller similar to an aeroplane propeller and a balance and guard ring surrounding the propeller, the ends of which latter are fastened to opposite polnts on the inner edge of the ring.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination iof parts hereinafter described, illustrated the accompanying drawing, and set forth 1n the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of constructlon within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Referring to the drawing:

Fig. 1 is a side elevation of the toy showing the manner of operating same.

Fig. 2 is a view similar to Fig. 1 with the operating mechanism and propeller shown in section.

Fig. 3 is a top plan view of the toy.

The embodiment of the invention shown in the accompanying drawing, comprlses a handle 1 having an enlarged socketed upper end 2. Mounted in the socket is a rotor 3 having a rounded inner end 4:, having a working fit with the inner end of the socket.

The rotor has a cylindrical portion 5 of less diameter than the end portion 4 and which terminates at a point flush with the upper end of the socket, at which point there is provided on the rotor, an enlarged cylin: drical head 6. This head 6 on its lower side is adapted to engage the outer end of the.

socket.

Extending from the handle through the center of and out beyond the socket, is a pin 7 on which the rotor is revolvable, there being a bore 8 through the rotor for reception of the pin. Alined openings 9 are formed in opposite sides of the socket and slidably re- 4' The cord arranged as described and shown,

holds the rotor in the socket.

The aerial or projectile member comprises a two blade propeller 13 having a central opening 14 for'reception of the pin 7. On the head 6 are stop pins 15 arranged to engage opposite sides of the propeller whereupon the propeller will turn upon rotation of the rotor. The blades of the propeller are so shaped and arranged that the pr jectile will ascend when rotated in a clockwise direction and when in a horizontal position. To stabilize the propeller and guard the same, I provide a wire ring 16 across which the propeller extends, the ends of the propeller being fastened to the ring.

To operate the toy, the aerial member is mounted in place with the pin 7 extending through the hole 14L and the stop pins engage with opposite sides of the propeller. By pulling the cord to the right, the rotor and aerial member are rotated and when the propeller reaches a certain velocity it will rise quickly and sail upwardly twenty feet or more in the air, dependent on the speed of rotation thereof. The ring protects the propeller from being bent or broken and acts as a safe guard to prevent injury to the operator or nearby persons who might be struck by the propeller.

The toy of my invention is harmless, simple, inexpensive and highly amusing. The construction and arrangement of the toy make it strong, durable and reliable in operation.

I claim:

A toy comprising a handle having a socket opening at one end thereof and provided with openings at opposite sides of the socket and a bore extending from the inner end of the socket longitudinally in the handle, a

rotor in the socket provided with an en- W largement on its innerend having a working fit in the socket, a pin extending through the rotor and rotatably engaging in said bore, an enlargement on the outer end of the rotor overlying and engaging the outer end of the handle, an aerial device detachably supported on the last named enlargement and a flexible cord extended through the openings and looped around said rotor.
